Description

Technical Field

[0001] This invention relates to the field of SMA connector technology, and more specifically, to an SMA structure with a jumper frame. Background Technology

[0002] Depending on the product design, the materials and thickness of jumpers used in actual applications vary. Thick jumpers are divided into ordinary jumpers for connecting different devices and crossover jumpers for connecting the same devices. The core of the jumper is generally relatively stiff, which is not conducive to bending. When bending, there will be obvious return loss, which will lead to a decrease in the performance of the cable. Thin jumpers are generally fixed to the frame of the circuit board by soldering and are often used for connecting various components on the circuit board.

[0003] The jumpers on the jumper frame connect the horizontal and vertical connecting ribs to ensure that current can flow between them. However, the existing jumper frames use a large number of jumpers, which takes a long time to solder and has strict size requirements. In addition, the jumper frames have pins soldered on them. When the pins are damaged, the solder needs to be remelted, which can easily damage the pads and is troublesome to disassemble and reassemble, resulting in high costs. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an SMA structure with a jumper frame. The technical problem to be solved by the present invention is that: the existing jumper frame uses a large number of jumpers, which takes a long time to solder and has strict size requirements; the jumper frame has pins soldered on it, and when the pins are damaged, the solder needs to be remelted, which can easily damage the pads and is troublesome to disassemble and assemble.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an SMA structure with a jumper frame, comprising a frame, a top shell at the top of the frame, a bottom shell at the bottom of the frame, a plurality of connecting ribs at the top of the frame, a jumper wire between two horizontal connecting ribs, welding slots inside both sides of the jumper wire, a mounting slot inside one side of the connecting rib, the jumper wire being located inside the mounting slot, a welding plate fixedly connected to the top of the front of the frame, a pin at the top of the welding plate, a fixing mechanism outside the pin, the fixing mechanism including a bottom clamping block, the top of the bottom clamping block contacting the bottom end of the back of the pin, and a top clamping plate movably connected to the top of the back of the pin.

[0006] In a preferred embodiment, the top shell is provided with a plurality of heat dissipation blocks, and the frame is provided with a plurality of heat dissipation grooves. The plurality of heat dissipation grooves are respectively located between two longitudinal connecting ribs. The use of heat dissipation grooves reduces the time that heat is concentrated on the frame, and the use of heat dissipation blocks helps to accelerate heat conduction and perform heat dissipation work inside the bottom shell and the top shell.

[0007] In a preferred embodiment, two pads are machined inside the mounting slot, and two inclined baffles are provided between the two pads. The two inclined baffles are fixedly connected to the connecting ribs. The two inclined baffles are located inside the welding groove. By opening the mounting slot and the welding groove, it is beneficial to reduce the amount of copper used and reduce the processing size requirements of the connecting ribs, thereby improving the product qualification rate.

[0008] In a preferred embodiment, an L-shaped clamping plate is fixedly connected to one side of the bottom clamping block, and a telescopic sleeve is hinged to the bottom end of one side of the top clamping plate. A positioning rod is movably sleeved inside the telescopic sleeve, and the bottom end of the positioning rod is fixedly connected to the L-shaped clamping plate. The use of the telescopic sleeve and the positioning rod helps to control the vertical movement of the top clamping plate and the bottom clamping block in the longitudinal direction, ensuring the clamping operation.

[0009] In a preferred embodiment, a retaining plate is fixedly connected to one side of the bottom of the telescopic sleeve, a top retaining plate is fixedly connected to the bottom of the retaining plate, a tensile spring is provided at the bottom of the top retaining plate, a bottom retaining plate is provided at the bottom of the tensile spring, and a clamping block connecting plate is fixedly connected to the bottom retaining plate. The clamping block connecting plate is fixedly connected to the bottom clamping block. The use of the tensile spring helps to pull the bottom clamping block and the top clamping plate closer to each other, ensuring that the welding piece and the pin are in close contact.

[0010] In a preferred embodiment, the top and bottom ends of the tensile spring are both fixedly connected to a connecting plate. The top end of the top connecting plate is fixedly connected to a connecting post, and the top end of the connecting post is fixedly connected to a limiting plate. The top limiting plate is pinned to the inside of the top retaining seat, and the bottom limiting plate is pinned to the inside of the bottom retaining seat. The use of the limiting plate and the connecting post facilitates the removal of the failed tensile spring from the bottom retaining seat and the top retaining seat.

[0011] In a preferred embodiment, the opening of the top retainer faces the back, and the opening of the bottom retainer faces the front. By having the openings of the bottom retainer and the top retainer face the front and back respectively, it is beneficial to prevent the limiting plate from disengaging from the inside of the top retainer and the bottom retainer during the movement of the telescopic sleeve, thus achieving a self-locking effect.

[0012] In a preferred embodiment, one end of the top clamping plate is fixedly connected to an angle plate, and a connecting bolt is movably connected inside the angle plate. A compression spring is movably sleeved on the top of the connecting bolt. The compression spring is located at the top of the angle plate, and the bottom of the connecting bolt is threaded to one side of the bottom clamping block. By sleeved the compression spring on the top of the connecting bolt and threadedly connected the bottom of the connecting bolt to the bottom clamping block, the force on both sides of the pin is uniform.

[0013] In a preferred embodiment, a prism block is fixedly connected to the top of the inner front side of the bottom shell, and a prism groove is opened at the bottom of the bottom clamping block. The prism block is located inside the prism groove. By using the prism block and the prism groove in conjunction, the movement of the bottom clamping block inside the bottom shell can be restricted.

[0014] In a preferred embodiment, a plurality of mounting pins are fixedly connected to the top of one side of the bottom shell. The plurality of mounting pins are located inside the frame. A limiting post is fixedly connected to the top of the welding piece. The limiting post is located inside the pin. By using the mounting pins and the limiting post, the sliding of the pin can be restricted by restricting the sliding of the frame.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention reduces copper usage and provides space for the jumper by placing it between two connecting ribs, allowing both sides of the jumper to fall inside the mounting slot. This also lowers the dimensional requirements of the connecting ribs during production and improves the product qualification rate. By filling the solder groove with solder and processing a pad inside the mounting slot, space can be provided for the solder to flow during the soldering process, avoiding the problem of cold solder joints. In addition, two inclined baffles can prevent the jumper from loosening between the jumper and the connecting ribs.

[0017] 2. The present invention is equipped with a fixing mechanism to connect the ridge groove and the ridge block, preventing the bottom clamping block and the top clamping plate from moving in the plane during clamping, thus ensuring the clamping effect. By pulling the tensile spring, the tension spring is stored to bring one side of the bottom clamping block and the top clamping plate closer to each other, so that the pin is tightly attached to the surface of the welding piece. In addition, the anti-compression spring sleeved on the top of the connecting bolt pushes the corner plate to move to the bottom, so that the pin is evenly stressed on both sides, ensuring stable signal transmission.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Refer to the instruction manual appendix Figure 1-4This embodiment of an SMA structure with a jumper frame includes a frame 3, a top shell 1 on the top of the frame 3, multiple heat sinks 2 inside the top shell 1, and multiple heat dissipation slots 11 inside the frame 3. The heat dissipation slots 11 are located between two longitudinal connecting ribs 10. The use of the heat dissipation slots 11 reduces the time heat is concentrated on the frame 3, and the use of the heat sinks 2 accelerates heat conduction, facilitating heat dissipation inside the bottom shell 6 and the top shell 1. A bottom shell 6 is located at the bottom of the frame 3, and multiple connecting ribs 10 are located at the top of the frame 3. Jumpers 16 are installed between two transverse connecting ribs 10. The side has a welding groove 14, and the side of the connecting rib 10 has a mounting slot 12. The jumper 16 is located inside the mounting slot 12. The mounting slot 12 has two pads 15, and two inclined baffles 13 are set between the two pads 15. The two inclined baffles 13 are fixedly connected to the connecting rib 10. The two inclined baffles 13 are located inside the welding groove 14. By opening the mounting slot 12 and the welding groove 14, it is beneficial to reduce the amount of copper used and reduce the processing size requirements of the connecting rib 10, thereby improving the product qualification rate. The top of the front of the frame 3 is fixedly connected to a welding piece 8, and the top of the welding piece 8 is provided with a pin 5.

[0032] The specific implementation scenario is as follows: In the use of this invention, the jumper 16 is first placed between the two connecting ribs 10 so that both sides of the jumper 16 fall inside the mounting slot 12. By burying both sides of the jumper 16 inside the mounting slot 12, the use of copper can be reduced. Then, two inclined baffles 13 are placed inside the welding slot 14 so that the bottom end of the jumper 16 contacts the top end of the pad 15. Finally, solder is added inside the welding slot 14 to fix the jumper 16 and the connecting ribs 10. The two inclined baffles 13 can prevent the jumper 16 and the connecting ribs 10 from loosening, ensuring stable signal transmission. By processing the pad 15 inside the mounting slot 12, space can be provided for the solder to flow during the welding process. In the actual use of the frame 3, the heat dissipation grooves 11 opened inside the frame 3 can accelerate the dissipation of heat from the inside of the frame 3. Then, the heat is absorbed by the multiple heat dissipation blocks 2 inside the top shell 1 and exchanged with the outside air to achieve a rapid cooling effect.

[0033] Refer to the instruction manual appendix Figure 5-11This embodiment of an SMA structure with a jumper frame includes a pin 5. A fixing mechanism 4 is provided outside the pin 5. The fixing mechanism 4 includes a bottom clamping block 41, the top of which contacts the bottom end of the back of the pin 5. An L-shaped clamping plate 413 is fixedly connected to one side of the bottom clamping block 41. A telescopic sleeve 46 is hinged to the bottom end of one side of a top clamping plate 45. A positioning rod 49 is movably sleeved inside the telescopic sleeve 46. The bottom end of the positioning rod 49 is fixedly connected to the L-shaped clamping plate 413. The use of the telescopic sleeve 46 and the positioning rod 49 facilitates the control of the vertical movement of the top clamping plate 45 and the bottom clamping block 41, ensuring clamping operation. The top end of the back of the pin 5 is movably connected to the top of the top clamping plate 45. One end of the top clamping plate 45... An angle plate 44 is fixedly connected, and a connecting bolt 42 is movably connected inside the angle plate 44. A compression spring 43 is movably sleeved on the top of the connecting bolt 42. The compression spring 43 is located at the top of the angle plate 44. The bottom of the connecting bolt 42 is threaded to one side of the bottom clamping block 41. By sleeved the compression spring 43 on the top of the connecting bolt 42 and threadedly connected the bottom of the connecting bolt 42 to the bottom clamping block 41, the force on both sides of the pin 5 is evenly distributed. A card seat connecting plate 47 is fixedly connected to one side of the bottom of the telescopic sleeve 46. A top card seat 48 is fixedly connected to the bottom of the card seat connecting plate 47. A tensile spring 410 is provided at the bottom of the top card seat 48. A connecting plate 416 is fixedly connected to both the top and bottom of the tensile spring 410. The connecting plate 416 is located at the top. A connecting post 414 is fixedly connected to the top of the receiving plate 416. A limiting plate 415 is fixedly connected to the top of the connecting post 414. The limiting plate 415 at the top is pinned to the inside of the top retaining seat 48, and the limiting plate 415 at the bottom is pinned to the inside of the bottom retaining seat 412. The use of the limiting plate 415 and the connecting post 414 facilitates the removal of the failed tensile spring 410 from the bottom retaining seat 412 and the top retaining seat 48. A bottom retaining seat 412 is provided at the bottom of the tensile spring 410. A clamping block connecting plate 411 is fixedly connected to the bottom of the bottom retaining seat 412. The clamping block connecting plate 411 is fixedly connected to the bottom clamping block 41. The use of the tensile spring 410 facilitates the pulling of the bottom clamping block 41 and the top clamping plate 45 closer together, ensuring the welding piece 8 The top bracket 48 has its opening facing the back, and the bottom bracket 412 has its opening facing the front. By having the openings of the bottom bracket 412 and the top bracket 48 face the front and back respectively, it helps to prevent the limiting plate 415 from disengaging from the inside of the top bracket 48 and the bottom bracket 412 during the movement of the telescopic sleeve 46, thus achieving a self-locking effect. A prism block 17 is fixedly connected to the top of the front side of the inner side of the bottom shell 6. A prism groove 417 is opened at the bottom of the bottom clamping block 41, and the prism block 17 is located inside the prism groove 417. By using the prism block 17 to cooperate with the prism groove 417, the movement of the bottom clamping block 41 inside the bottom shell 6 can be restricted. Multiple mounting pins 7 are fixedly connected to the top of one side of the inner side of the bottom shell 6. The multiple mounting pins 7 are located inside the frame 3.A limiting post 9 is fixedly connected to the top of the welding piece 8. The limiting post 9 is located inside the pin 5. By using the mounting pin 7 and the limiting post 9, the sliding of the pin 5 can be restricted by limiting the sliding of the frame 3.

[0034] The specific implementation scenario is as follows: In the use of this invention, the bottom clamping block 41 is placed on top of the prism block 17, so that the prism groove 417 is connected to the prism block 17. This can prevent the bottom clamping block 41 and the top clamping plate 45 from moving in the plane during clamping, ensuring the clamping effect. Then, the processed frame 3 is stably installed inside the bottom shell 6 by the mounting pin 7. After the pin 5 is connected to the limiting post 9, it can prevent the pin 5 from sliding in the plane. Then, the telescopic sleeve 46 slides upward outside the positioning sleeve 49. The card seat connecting plate 47 pulls the tensile spring 410, storing force for the tensile spring 410 and causing the top clamping plate 45 to move around the top of the telescopic sleeve 46 and back to the pin 5. The top ends of the surfaces come into contact with each other, and finally the connecting bolt 42 with the anti-compression spring 43 on the top is threaded through the inside of the corner plate 44 and connected to the bottom clamping block 41. After the installation of the fixing mechanism 4 is completed, the top end of the L-shaped clamping plate 413 comes into contact with the bottom end of the frame 3. The stored tension spring 410 makes one side of the bottom clamping block 41 and the top clamping plate 45 move closer to each other, so that the pin 5 is tightly attached to the surface of the welding piece 8. In addition, the anti-compression spring 43 on the top of the connecting bolt 42 pushes the corner plate 44 to the bottom, so that the two sides of the pin 5 are evenly stressed, ensuring stable signal transmission. The present invention facilitates the installation and removal of the pin 5 by using the fixing mechanism 4, which is convenient, quick and will not damage the welding piece.

[0035] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
